Comment 159 for bug 1488719

"I think the flickering problem only occurs if you use two external monitors with e-port-dock."

In my case, my laptop suddenly powers off. But another bug that happens in it is this: after a while with Xscreensaver running, the screen flickers and remains that way for some 3 extra seconds after I type my password and the screen is unlocked.

Weird thing is that after the screen is unlocked, some 3 seconds later the flickering stops.
